摘要： A solenoid-operated cutoff valve for use with fuel cells has a movable member disposed in a guide housing for displacement upon energization of a solenoid. When the movable member is displaced, a pilot valve is unseated from a pilot valve seat. A fluid in a communication chamber flows through a pilot passage into an output port. The communication chamber is divided into a first communication chamber and a second communication chamber by a diaphragm. Under a pressure difference developed between the first communication chamber and the second communication chamber, a main valve of a valve head is unseated from a valve seat of a valve housing, opening the solenoid-operated cutoff valve.

摘要： A variable flow-rate ejector for precisely controlling the flow rate based on pressure is disclosed. The ejector has a simple mechanical structure which comprises a nozzle for ejecting a first fluid; a diffuser into which a second fluid is drawn due to a negative pressure produced around the first fluid, where the first and second fluids are merged; a third-fluid chamber formed by first and second diaphragms attached to the needle, and the body of the ejector; and a fourth-fluid chamber formed by the second diaphragm and the body. The area of an opening around the needle in the opening at the head of the nozzle is changed by displacement of the needle along the central axis according to movement of first and second diaphragms which move in accordance with the pressure produced by the first fluid, the third fluid, and the fourth fluid.

摘要： A sheet feeder includes a sheet loading tray, an air blower, a side air blower, and processing circuitry. The sheet loading tray loads sheets. The air blower blows air to the sheets to float and separate the sheets. The side air blower blows air to the sheets to separate the sheets. The processing circuitry controls a tray elevator to rise the sheet loading tray to move the sheets to an upper limit position, after a predetermined time has elapsed from a time when the sheets are loaded on the sheet loading tray. The processing circuitry causes the air blower and the side air blower to blow air to the sheets to perform sheet separation and controls the tray elevator to lower the sheet loading tray to a position at which an intermediate remaining-sheet sensor is disposed, after the sheet separation ends.

摘要： A sheet feeding apparatus includes a sheet stacker, an air blower, a suction feeder, a lifting mechanism, an elevation detection sensor, an elevation detection sensor, a feed detection sensor, and processing circuitry. The air blower blows air to float an uppermost sheet of sheets stacked on the sheet stacker. The processing circuitry drives the lifting mechanism such that the sheet stacker is lifted by an elevation amount determined based on a sheet thickness of the sheets stacked on the sheet stacker, each time a sheet is detected when a number of sheets detected is smaller than a threshold number of sheets, and stops lifting of the sheet stacker until a sheet is not detected when the number of sheets reaches the threshold number of sheets, while repeatedly feeding the uppermost sheet and counting the number of sheets.
